Hi,
Spyder seems to have a couple issues with taking control of figure
properties without asking. Any ideas as to how to avoid these issues?
1) I've noticed that when plotting from Spyder via an ipython or python
console, the figure size is limited to 12 inches wide by 6.725 inches tall
(see below example script), when using the default dpi (different dpi
changes the maximums). When running the script directly from python or
ipython command line, the maximum height is not reached and goes to 8
inches tall as specified in the script.
from pylab import *
figs = []
w = 5
h = 5
for i in xrange(4):
figs.append(figure(figsize=(w, h)))
plot([1,2,3],[6,4,2])
h = h+1
show()
for each in figs:
print each.get_size_inches()
The output is:
[ 5. 5.]
[ 5. 6.]
[ 5. 6.725]
[ 5. 6.725]
2) A seemingly related issue-
Running the following in Spyder:
from pylab import *
fig=figure(figsize=(5,5))
plot([1,2,3],[6,4,2])
show()
fig.get_size_inches()
...gives a square figure window and the console output as expected:
[ 5. 5.]
However, running the following which specifies a different dpi:
from pylab import *
fig=figure(figsize=(5,5), dpi=50)
plot([1,2,3],[6,4,2])
show()
print fig.get_size_inches()
...gives a rectangular figure window and the console output:
[ 6.46 5. ]
So Spyder does not seem to be handling the dpi properly.
I tried it with Spyder 2.0.12 and the latest 2.1.8.
In the 2nd example with dpi, running directly from ipython or python
command line gives square figures but with reported dimensions slightly
larger than 5x5 inches. Adding these 2 lines to the start of the scripts:
import matplotlib as mpl
mpl.use('QT4Agg')
...makes it give 5x5 inches for both figures. (Adding those 2 lines to the
start when running from Spyder has not effect since Spyder consoles have
already chosen QT4Agg as the GUI backend.
Best,
Chris
